• using-local-clock - using local clock as time source (server enabled while client disabled)<br />

Example<br />

To enable the NTP client to synchronize with the 159.148.60.2 server:<br />

[admin@<strong>MikroTik</strong>] system ntp client> set enabled=yes primary-ntp=159.148.60.2<br />

[admin@<strong>MikroTik</strong>] system ntp client> print<br />

enabled: yes<br />

mode: unicast<br />

primary-ntp: 159.148.60.2<br />

secondary-ntp: 0.0.0.0<br />

status: synchronized<br />

[admin@<strong>MikroTik</strong>] system ntp client><br />

Server<br />

Home menu level: /system ntp server<br />

Property Description<br />

broadcast (yes | no; default: no) - whether NTP broadcast message is sent to 255.255.255.255<br />

every 64s<br />

enabled (yes | no; default: no) - whether the NTP server is enabled<br />

manycast (yes | no; default: yes) - whether NTP server listens for multicast messages sent to<br />

239.192.1.1 and responds to them<br />

multicast (yes | no; default: no) - whether NTP multicast message is sent to 224.0.1.1 every 64s<br />

Notes<br />

NTP server activities only when local NTP client is in synchronized or using-local-clock mode.<br />

If NTP server is disabled, all NTP requests are ignored.<br />

If NTP server is enabled, all individual time requests are answered.<br />

CAUTION! Using broadcast, multicast and manycast modes is dangerous! Intruder (or simple<br />

user) can set up his own NTP server. If this new server will be chosen as time source for your<br />

server, it will be possible for this user to change time on your server at his will.<br />

Example<br />

To enable NTP server to answer unicast requests only:<br />

[admin@<strong>MikroTik</strong>] system ntp server> set manycast=no enabled=yes<br />

[admin@<strong>MikroTik</strong>] system ntp server> print<br />

enabled: yes<br />

broadcast: no<br />

multicast: no<br />

manycast: no<br />
